ranges: Defines vector as range

In lsasim: Functions to Facilitate the Simulation of Large Scale Assessment Data

Defines vector as range

Description

Redefines the class of a vector as "range"

Usage

ranges(x, y)

Arguments

x	first element
y	second element

Value

'c(x, y)', but with the "range" class

Note

This function was created to be used as an element in the 'N' argument of 'cluster_gen'. The name was chosen to avoid conflict with 'base::range()'.

'ranges()' should always be used within a 'list()'. Inserting a "range" vector inside a common vector ('c()') will result in a common vector. For example, 'c(3, ranges(8, 10))' is the same as 'c(3, 8, 10)', because when faced with conflicting classes in the same element, R will resolve to the simpler case ("numeric", in this case). An easier way to understand this concept is by checking 'class(c(3, "a"))' is "character", meaning the number 3 was devolved into a character "3".
